文章介绍：本篇主要介绍在华为交换机中怎么配置DHCPv6无状态下发IPv6地址，主要应用场景是，企业需要使用ipv6进行业务测试，比如谷歌兼容性测试套件CTS，对IPv6网络要求就比较严格，经过调试测试，总结出这篇指导性文章，仅供参考。
一、网络拓扑
二、拓扑说明
- 华为AR路由器作为出口网关对接运营商，配置nat等基础网络配置；
- 华为核心交换机作为用户的网关，配置dhcpv4和dhcpv6，策略路由等基础网络配置；
- 华为无线控制器AC管理无线AP，配置多SSID，提供用户无线接入；
- 加速路由器Router，旁挂核心交换机，路由ipv6地址给华为核心交换机，同时配合华为核心交换机配置的策略路由实现ipv4海外加速需求。
